2、在source端创建测试表空间

select tablespace_name,
	status 
from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
UNDOTBS1                       ONLINE
SYSAUX                         ONLINE
TEMPTS1                        ONLINE
USERS                          ONLINE
OUTLN                          ONLINE

6 rows selected.

select file_name from dba_data_files;

FILE_NAME
------------------------------------------------
/u01/app/oracle/oradata/normal/system01.dbf
/u01/app/oracle/oradata/normal/undotbs01.dbf
/u01/app/oracle/oradata/normal/sysaux01.dbf
/u01/app/oracle/oradata/normal/users01.dbf
/u01/app/oracle/oradata/normal/undotbs02.dbf
/u01/app/oracle/oradata/normal/system02.dbf
/u01/app/oracle/oradata/normal/outln01.dbf

7 rows selected.

--创建表空间创建表空间 tset
create tablespace tset datafile '/u01/app/oracle/oradata/normal/test01.dbf' size 50M;
Tablespace created.

--创建用户source_test，并指定表空间

--在source端
create user source_test 
identified by oracle 
default tablespace tset 
temporary tablespace TEMPTS1;

User created.

grant connect,resource to source_test;

Grant succeeded.

--在target端（暂时只先创建用户）
create user target_test 
identified by oracle
temporary tablespace TEMPTS1;

User created.

grant connect,resource to target_test;

Grant succeeded.

--创建测试表
SQL> conn source_test/oracle
Connected.
SQL> create table t1(id number, name varchar2(30));

Table created.

SQL> insert into t1 values(1, 'AAAAA');

1 row created.

SQL> insert into t1 values(2, 'BBBBB');

1 row created.

SQL> commit;

Commit complete.

select * from t1;

        ID NAME
---------- ------------------------------
         1 AAAAA
         2 BBBBB

3、在source端和target端创建 backup 的目录

[oracle@normal ~]$ mkdir -p /u01/backup
[oracle@normal ~]$ ls -l /u01
total 24
drwxr-xr-x 3 oracle oinstall  4096 Jul 28 12:31 app
drwxr-xr-x 2 oracle oinstall  4096 Sep 14 16:21 backup

SQL> show user
USER is "SYS"
SQL> create directory backup as '/u01/backup';

Directory created.

SQL> col owner format a5
SQL> col directory_name format a25
SQL> col DIRECTORY_PATH format a50	

SQL> select * from dba_directories;	 
OWNER DIRECTORY_NAME            DIRECTORY_PATH
----- ------------------------- --------------------------------------------------
SYS   BACKUP                    /u01/backup
SYS   OUTLN_DIR                 /home/oracle
SYS   DATA_PUMP_DIR             /u01/app/oracle/product/11.2.0/db_1/rdbms/log/
SYS   ORACLE_OCM_CONFIG_DIR     /u01/app/oracle/product/11.2.0/db_1/ccr/state

SQL> GRANT read, write ON DIRECTORY backup TO source_test;

Grant succeeded.

--在target端
[oracle@test ~]$ mkdir -p /u01/backup
[oracle@test ~]$ ls -l /u01
total 24
drwxr-xr-x 3 oracle oinstall  4096 Aug 28 09:09 app
drwxr-xr-x 2 oracle oinstall  4096 Sep 14 16:40 backup

SQL> show user
USER is "SYS"
SQL> create directory backup as '/u01/backup';

Directory created.

SQL> col owner format a5
SQL> col directory_name format a25
SQL> col DIRECTORY_PATH format a50
SQL> select * from dba_directories;

OWNER DIRECTORY_NAME            DIRECTORY_PATH
----- ------------------------- --------------------------------------------------
SYS   BACKUP                    /u01/backup
SYS   OUTLN_DIR                 /home/oracle
SYS   DATA_PUMP_DIR             /u01/app/oracle/product/11.2.0/db_1/rdbms/log/
SYS   ORACLE_OCM_CONFIG_DIR     /u01/app/oracle/product/11.2.0/db_1/ccr/state

SQL> GRANT read, write ON DIRECTORY backup TO target_test;

Grant succeeded.

4、检查表空间自包含（就是改表空间里的数据没有和其他表空间数据有关联，如果有关联会报错）

SQL> execute dbms_tts.transport_set_check('TSET', TRUE);

PL/SQL procedure successfully completed.

--查看自包含验证结果：
SQL> select * from transport_set_violations;

no rows selected
--没有记录说明没有错

5、将表空间TSET设置成read--only

SQL> alter tablespace TSET read only;

Tablespace altered.

select tablespace_name,
	status 
from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
UNDOTBS1                       ONLINE
SYSAUX                         ONLINE
TEMPTS1                        ONLINE
USERS                          ONLINE
OUTLN                          ONLINE
TSET                           READ ONLY

7 rows selected.

6、生成：Transportable Tablespace Set

Transportable Tablespace Set有两部分：

1.expdp 导出的表空间的metadata

2.还有就是表空间对应的数据文件

--expdp 导出的表空间的metadata	 
[oracle@normal normal]$ pwd
/u01/app/oracle/oradata/normal
[oracle@normal normal]$ ll
total 2294664
-rw-r----- 1 oracle oinstall   9781248 Sep 14 16:46 control01.ctl

[oracle@normal normal]$ expdp dumpfile=test01.dmp directory=backup transport_tablespaces=TSET transport_full_check=y logfile=TSET.log

7、将Transportable Tablespace set 传送到Target端

1）将表空间test 对应的数据文件copy到Target 对应的ORADATA目录下。

2）将expdp 导出的表空间metadta 数据copy 到Target 端的backup 目录下

--将表空间test 对应的数据文件copy到Target 对应的ORADATA目录下。
[oracle@normal normal]$ scp /u01/backup/test01.dmp 192.168.137.12:/u01/backup
oracle@192.168.137.12 s password: 
test01.dmp                                  100%   76KB  76.0KB/s   00:00 
		 
--将expdp 导出的表空间metadta 数据copy 到Target 端的backup 目录下	 
[oracle@normal normal]$ scp test01.dbf 192.168.137.12:/u01/app/oracle/oradata/normal/test01.dbf
oracle@192.168.137.12 s password: 
test01.dbf                                  100%   50MB  16.7MB/s   00:03  

--在target端查看文件是否已经传输
[oracle@test ~]$ ll /u01/backup/             
total 76
-rw-r----- 1 oracle oinstall 77824 Sep 14 17:03 test01.dmp

[oracle@test ~]$ ll $ORACLE_BASE/oradata/normal/test01.dbf
-rw-r----- 1 oracle oinstall 52436992 Sep 14 17:04 /u01/app/oracle/oradata/normal/test01.dbf

8、在Target 系统上Import 表空间的metadata(使用target_test用户，需要用到remap_schema)

[oracle@test ~]$ impdp directory=backup dumpfile=test01.dmp transport_datafiles=/u01/app/oracle/oradata/normal/test01.dbf remap_schema=source_test:target_test logfile
=test.log

Starting "SYS"."SYS_IMPORT_TRANSPORTABLE_01":  /********/ AS SYSDBA directory=backup dumpfile=test01.dmp transport_datafiles=/u01/app/oracle/oradata/normal/test01.dbf remap_schema=source_test:target_test logfile=test.log

Processing object type TRANSPORTABLE_EXPORT/TABLE
Processing object type TRANSPORTABLE_EXPORT/POST_INSTANCE/PLUGTS_BLK
Job "SYS"."SYS_IMPORT_TRANSPORTABLE_01" successfully completed at 17:09:55

9、查看并修改表空间状态

select tablespace_name,
	status 
from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
UNDOTBS1                       ONLINE
SYSAUX                         ONLINE
TEMPTS1                        ONLINE
USERS                          ONLINE
OUTLN                          ONLINE
TSET                           READ ONLY

7 rows selected.

SQL> alter tablespace TSET read write;

Tablespace altered.

10、验证

SQL> conn target_test/oracle
Connected.

SQL> select * from t1;

        ID NAME
---------- ------------------------------
         1 AAAAA
         2 BBBBB
